Improvement in friction-brakes for cotton-lapping machines



To all whom it 'may concern:

i Be it known that I, EDWARDVAN WINKLE, of

Paterson, in the'county of Passaic, and State of New EDWARD VAN WIN'KLE,or PATERson'NEW JERSEY.

Letters Patent Afa. 93,649, dated August l0, 1869.

IMPROVEMENT IN l FRICTION-BRAKES FOR. COTTON-LAPPING- MACHINES.

The Schedule referred to in these Letters Patent and making part of theSame.

Jersey, have 'invented a new and improved Friction- Attachrnent toOotton-.Iiappers; and Iy do hereby declare that the following is a full,clear, and exactjdescription thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichnFigure rl represents a front elevation, partly in section, of myimproved friction-attachment to cotton-v lappers.

Figure 2 same, taken on the plane of the line x .v, iig. 1.

Similar letters of reference indicate like parts. The object of thisinvention is to produce an adjustable frictionattachment for thosermachines thronghwhich the cotton is passed, preparatory to its beingcarded, and which are usually termed cottonlappers.

The frictionattachlnents heretofore in usewere genorally but a system ofweights, connected with the lap-roller; they were in no casev soxarranged that,I whatever may be the wear of the friction-surfaces, thedegree of friction remains always the same.

lnKitsons patent friction-attachment, where two ,A

cheek-flanges, covered with leather, are used, the friction is, by shortwear of the cheeks, so reduced as to produce laps much lighter' thanthose for which the apparatus was originally adjusted.

My invention consists chiefly inthe application of two conicaltiiction-clutohes, one being stern-shaped, `and the other a'cup. Theformer is attached to the axle to be detained, and the other slidesloosely on that axle, and is pivoted to a weighted arm.

lVhen this arni is not otherwise raised, itwill always automaticallyhold the clutches together, to have the friction applic-(hand astheweight is adjustable on the rod, the degree ot' friction can alwaysberegu` lated. y

A, in the drawing, representsthe frame of my improved cotton-lapper. yB' Bare the two bed-rollers of the saine.

is a vertical transverse section of the- C is the lap-roller. It fitswitli its ends under the books a a of the toothed bars D, as usual. Y

vThe toothed bars mesh respectively into pinionsb b that are mounted ona horizontal shaft, E, which shaft has its hearings in the frame A.

On the shaft E is mounted a somewhat conical wheel, F, the rirnrof whichis covered with leather, or equivalent material.

G is a cup, sliding loosely on the shaft E, its inner diameter being aslarge as and shaped to correspond f with the outer surface of the wheelF, leather, or its and thereby also to the lap-roller.

If the 'friction-faces of the :clutches F G should wear, the degree offriction will remain the same, as the weight will have so much moredownward play, to keep them together.

When, by means of a lever, J, the weight is raised, the friction is, ofcourse, released.

The weight I is clamped to the lever H, in the desired position, bymeans of a screw, e.

The part G of the clutch may, if desired, be made stationary, and Esliding, instead of otherwise, if desired.'

I do not claim the conical frictionclutches perse, as I am awarethatthey have been used before; but

What I do 'clailmand desire to secure by Letters Patent, is

:The arrangement of the elbow-lever H and its.ad instable weight I, incombination with the male and female conesF Gr, Ysubstantially as shownand described, for the purpose set forth.v
